Did some more testing (only iRacing). This actually impacts the performance negatively when there’s not much CPU headroom left. At least in the case of iRacing. So use it only when you’re limited by the GPU.
I got my the settings such that the CPU and GPU are pretty evenly matched in terms of bottlenecking. Applied the vrperfkit with default settings. This caused a CPU bottleneck. 10 fps drop, GPU not fully utilized. Maybe the openvr_fsr (not for iRacing) performs better when the performance is also close to being CPU limited.
It won’t on white text on black unless the local dimming is per pixel as he says. Then the black will be as good as my TV. In scenes where there is black amongst bright - such as in forests and trees, it gets a little less dark, but not by much.
They should implement these things at driver level. The FFR they used uses an older version of FFR before VRS was developed by Nvidia. It rarely works and when it does it doesn’t offer much performance gain. If they switched to fholgers, they’d see more improvement in gains and it would work in every game if programed correctly. fholger deatiled the difficulty is knowing the eye rendering pattern (LRLRLR or RLRLRL RRLLRR etc.) as each game is different. They really need to bake VRS and FSR into the games in some way.
I tried it without Reshade to be safe, but I normally do use Reshade. FSR/NIS scaling work (but looks really bad), but not foveated rendering. Ideally I want to use just FFR + CAS Sharpening.
hi guys, i have a problem with starting iracing sim with the vr perf kit. i just did a clean install of iracing, then downloaded release 3.0 of the perf kit and copied the 2 files into the iracing main folder.
after i did this i can start the iracing launcher, but when i will start a test drive or anything else i get an error message after a couple of seconds saying: coul not find sim.
When i delete the 2 files again everything with iracing works normal.
Any idea what’s causing this problem?
